Picking the Right Shingle
Shingles come in three broad grades. Flat three-tab shingles are the thinnest and cheapest. Architectural, or dimensional, shingles are thicker and layered for texture. Impact-rated shingles are built to take hail better, worth asking about where damaging hail peaks in May and June.
The shingle is only half the decision. Underlayment, ice barrier, starter strips, ridge vents and flashing keep much of the water out, so ask that each be named on the bid.
Typical Reasons to Request Shingle Roof Replacement
- Granules in the gutters. Heavy grit at the downspouts means shingles are shedding their surface.
- Curled or cupped edges. Lifted corners let wind and water get underneath.
- Ice at the eaves. Winter ice ridges can push meltwater under shingles.
- Daylight or damp in the attic. Light through boards or stained sheathing deserves a look.
- Bruised shingles after hail. Scattered soft spots can be hail marks, which a roofer can confirm.
Cost Factors for Shingle Roof Replacement
The shingle grade matters less than you might expect. Tear-off, decking repairs, pitch and cuts around dormers and chimneys usually move the total more.
| Cost row | Figure | Source (year) |
|---|---|---|
| Whole roof, Illinois average | about $6,525 (typical range $5,081–$16,643) | This Old House (2026) |
| Asphalt shingles, Illinois average | about $4.70 per sq ft | This Old House (2026) |
| Asphalt shingles, Rockford | $5–$7 per sq ft | HomeBlue (2024, dated) |
| Metal, Illinois average | about $8.77 per sq ft | This Old House (2026) |
| Steel metal roofing, Chicago area | $6–$16 per sq ft | Angi (no date given) |
The calculator prices architectural shingles from $4.70 to $7.00 per square foot of roof surface, from the statewide 2026 average to the older Rockford figure.
The Usual Sequence
- Count the layers. Under Rockford's two-layer cap for most roofing, a house already wearing two gets stripped.
- Pick the shingle and color. View samples in sun and overcast light.
- Contract and permit. After you sign, the roofer files for the city permit, often through the online portal.
- Strip to the deck. Rotten sheathing is replaced.
- Protect the eaves. Rockford's re-roofing memo requires ice barrier when eaves show past ice damage, when the old roof had it, or when the shingle maker calls for it. It runs at least 24 inches inside the exterior wall line.
- Underlayment, shingles and vents. Starter course, shingles, flashing and ridge vent follow.
- Cleanup and final inspection. Nails get swept with a magnet, then the city inspects.
The Difference a Local Match Makes
Rules differ from one town to the next. Rockford follows the 2021 code cycle with local amendments. In Belvidere, re-roofs get two inspections, one of them for the required ice-and-water shield. Byron, IL lists re-roofing among the jobs that need a permit (815-440-2146). A roofer who works these towns weekly keeps them straight.
- Your deductible, waived or rebated. Under 815 ILCS 513/18(b), Illinois contractors may not advertise or promise it.
- A bid missing the license number. The roofer's licensed name and number are required on Illinois bids. Look both up on IDFPR's site.
- A plan to lay a third layer. Rockford's two-layer cap rules it out.
- No ice barrier on the bid. If the old roof had one or the eaves show ice damage, leaving it off falls short of the city's memo.
What People Want to Know
Are impact-rated shingles worth it here?
They cost more than standard architectural shingles and are designed to stand up better to hail. Whether that pays off depends partly on your insurer, since discounts for impact-resistant roofs vary by carrier in Illinois. Get a price for both on the same bid and call your insurer.
Can I pick any color in a historic district?
Not on your own. Homes in Rockford's historic districts need the preservation commission's approval before a roofing permit can be issued, and a noticeable change in color or style may draw questions. Your roofer can help put together the samples and photos the commission wants to see.
When is the best time to re-roof?
Shingles seal best in mild, dry weather, which is why spring and fall fill up fast. Winter work can still happen on warmer days with the right products. If you want the roof finished before the holidays and Stroll on State the Saturday after Thanksgiving, book the inspection early.
Do I need to be home during the work?
Not the whole time, but stay reachable while the job runs. The roofer may need into the attic or want a driveway spot for the dumpster. Move cars, patio furniture and fragile wall hangings before tear-off starts, since the hammering shakes the whole house.
Other Roof Work
Still deciding on materials? Metal roof replacement lays out the trade-offs. If only part of the roof is worn, start with roof repair. Hail marks? See storm and hail damage or the cost guide.
